We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

| Statement Concerning Quality of the MISR Ancillary Geographic Product September 19, 2000 | Here is a description of the **Statement_Quality_MISR_Ancillary_Geographic_09192000.pdf** document: This document is a Quality Statement for the MISR Ancillary Geographic Product (AGP), dated September 19, 2000, covering version F01_24. The AGP is a set of 233 pre-computed static files—one per Terra orbital path—that provide essential geographical data used as input by MISR production software to generate higher-level MISR products. The product contains eleven data fields organized into four groups: geographical locations (latitude/longitude), elevation data at both 1.1 km and 17.6 km resolution, surface orientation data (azimuth and zenith angles), and land/water identification—all defined on a Space Oblique Mercator (SOM) map projection grid. The statement assesses the quality of each data group, noting that most fields directly reflect the quality of their input datasets (including DTED, DCW Hypsography, ETOPO5, and World Vector Shoreline), though some resampling-related quality reductions were identified, particularly in regions with high relief, and the standard deviation of mean surface slope was flagged as unreliable. |
